Grapevine plant named ‘Sugrafortyfive’

ABSTRACT

A new and distinct grapevine variety ‘Sugrafortyfive’ is characterized by the production of a medium-sized, dark berry with near black skin color and an ellipsoidal, elongated shape. The berries of ‘Sugrafortyfive’ ripen early and are firm and very juicy. The new variety ‘Sugrafortyfive’ has a similar harvest time as ‘Summer Royal’ (unpatented) but the shape of the berry of the new variety ‘Sugrafortyfive’ is ellipsoidal elongated compared to round for ‘Summer Royal’.

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘SUGRAFORTYFIVE’.

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a new and distinct variety of grapevine, ‘Sugrafortyfive’, as herein described and illustrated. The new variety was first discovered by Michael J. Striem in July 2006 and selected as breeder number ‘03082-193-393’ by Terry A. Bacon in Wasco, Kern County, Calif. The variety was originated by controlled hybridization.

The new variety ‘Sugrafortyfive’ is characterized by the production of a medium-sized, dark berry with near black skin color and an ellipsoidal, elongated shape. The berries of ‘Sugrafortyfive’ ripen early and are firm and very juicy.

The seed parent is the varietal selection ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749) and the pollen parent is the varietal selection ‘Sugrathirteen’ (U.S. Plant Pat. No. 10,434). The parent varieties were first crossed in May 2003. The date of first sowing was March 2004, and the date of first flowering was May 2006.

The new variety ‘Sugrafortyfive’ was first asexually propagated in December 2007 in Wasco, Kern County, Calif., by Terry A. Bacon using hardwood cuttings.

The new variety ‘Sugrafortyfive’ looks similar to its pollen parent ‘Sugrathirteen’ (U.S. Plant Pat. No. 10,434) and has a similar berry color. However, the two varieties differ in that the harvest start date is about July 3 for the new variety ‘Sugrafortyfive’ compared to July 20 for Sugrathirteen (U.S. Plant Pat. No. 10,434).

The new variety ‘Sugrafortyfive’ has the same berry color as its seed parent ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749). However, it differs from its seed parent ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749) in that the berry shape is ellipsoidal and elongated for the new variety ‘Sugrafortyfive’ compared to ovate for the berries of ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749). Additionally, the new variety ‘Sugrafortyfive’ ripens earlier, starting on July 3 compared to July 21 for ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749).

Harvest of the new variety ‘Sugrafortyfive’ starts at about the same time as ‘Summer Royal’ (unpatented) but the shape of the berries of the new variety ‘Sugrafortyfive’ is ellipsoidal and elongated compared to a round shape for ‘Summer Royal’ (unpatented).

The new ‘Sugrafortyfive’ variety has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings.

Variations of the usual magnitude from the characteristics described herein may occur with changes in any of a variety of factors such as growing conditions, irrigation, fertilization, pruning, management and climatic variation.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new grape variety ‘Sugrafortyfive’.

The illustration shows the upper and lower surfaces of the leaves, the grape bunch and exterior and sectional views of the fruit.

The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England, 1986.

Many of the descriptive values in this specification are based on and conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997, which was developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).

The descriptive matter which follows pertains to ‘Sugrafortyfive’ plants grown in the vicinity of Wasco, Kern County, Calif. during 2014, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
